BACKGROUND: Nutritional rickets contributes to the high burden of illness and death among Ethiopian children below 5 years of age. Lack of adequate information appears to have negatively influenced the impact of prevention and treatment programs.
OBJECTIVES: The objective of this systematic review is to review existing body of knowledge about nutritional rickets in Ethiopia and develop recommendations that will guide development of strategies for effective interventions and research.
METHODS: Published and unpublished information on nutritional rickets in Ethiopia was collected systematically. The information was critically reviewed and discussed in the context of regional and global situation.
RESULTS: The major cause of nutritional rickets in Ethiopian children is lack of exposure to sunshine and/or inadequate intake of vitamin D. Lack of awareness and traditional beliefs are major causes for not exposing infants to sunshine. The disease is associated with poor socioeconomic status, low birth weight, protein-energy malnutrition and common childhood infections. Severe form of rickets is commonly seen at about 18 months of age. Rickets predisposes Ethiopian children to pneumonia. Diagnostic criteria used in most studies include two or more clinical signs and a characteristic radiological or biochemical abnormality. There are critical gaps in our knowledge about the epidemiology, ecology, and potentially effective interventions to prevent and treat rickets in Ethiopian children.
CONCLUSION: Most of the studies on nutritional rickets in Ethiopia have been conducted in hospital settings. There is a need for well designed epidemiological and ecological studies. The biologic basis for the striking association between PEM and active rickets seen in Ethiopia needs to be determined The role of calcium deficiency, the part played by genetic factors, the nature of the association between the duration of breastfeeding and rickets, and the role of complimentary feeds in Ethiopian children need to be explored. Studies are required to determine the amount of sunshine required to prevent rickets in Ethiopian infants. Studies are required to establish criteria for the diagnosis of clinical and sub clinical rickets, particularly in malnourished children. Prevention programs need to be pursued consistently and systematically and treatment options, including the single massive dose of vitamin D, need to be re-evaluated and optimal mode of treatment determined.

Abstract of May 2017 conference presentation
"The majority of nutritional rickets worldwide is thought to be driven by vitamin D deficiency due to inadequate skin exposure to UVB-containing sunshine. In many countries in Africa however, 25-hydroxyvitamin D concentrations (the status marker for vitamin D) are above those generally associated with vitamin D deficiency thus indicating alternative causes of rickets"
Comment by the founder of VitaminDWiki
The children with rickets in Africa all had > 10 ng of vitamin D.
Vitamin D is lnown to increase amount of Calcium getting into the body
Perhaps African/dark skinned children need MORE than other children
Wonder if anyone has ever tried giving Vitamin D to African children with Rickets?
